SPECIFICATION forming part of Letters Patent No. 392,064, dated October 30,1888. Application tiled February 3, 1888. Serial No. 262,887. (No model.)

To @ZZ whom, t may concern.-

Be it known that I, JONATHAN PILKING TON, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Machines for Making Nails; and I do hereby declare that the following is a full, clear, and

exact description thereof.

My invention relates to self-feed nail-maklo ing machines; and it consists in certain peculiarities of construction and combination of parts, to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents in side elevation the feedbarrel of a nail-machine and the application of my invention; Fig. 9, a longitudinal vertical section of the same on the line 2 2 of Fig. 1, and Fig. 3 an end 2o view.

Referring by letter to the drawings, A rcpresents the barrel of a nail-cutting machine, and B the guidefingers for the nail-plates, these paris being of the ordinary construction, except that the nose G of said barrel has an opening, D, cut in each side thereof'.

Bolted or otherwise suitably secured to the barrel-nose O are spring-fingers E, and each one of these fingers has a thick forward end, 3o F, that enters an adjacent one of the openings D in said nose.

In order that the spring-fingers E may be longitudinally adjusted,I provide the rear end of each one with alongitudinal slot, G1, for engagement with asetscrew, H, that engages the nose C of the barrel A, this being the preferred method of securing said fingers in operative position.

The spring-lingers E are adjusted to have 4o their forward ends impinge against the edges of a nail-plate being fed to the machine, and owing to their elasticity said lingers will yield to any irregularities in the width of said nailplate, thereby preventing any sticking of this l5 plate or wear on the nose of the feed-barrel and insuring a perfect cutting of the nailblanks.

By placing washers under the rear ends of the spring-fingers the forward ends of the latter can be brought farther into the nose C of 5o the barrel A, `and thus an adjustment is effected to accommodate nail-plates of a less width than that for which said barrel may have been originally intended. The springfingers also permit the feeding of awidernailplate than that for which the barrel may have been intended.

My invention can be readily applied to any feed-barrel, and by its employment said barrel Will last an indefinite length of time,where 6o as an ordinary barrel soon becomes worn out at the nose, and is then worthless and has to be replaced by a new one.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, :is-

l. The feed-barrel ofa nail-cutting machine, in combination with longitudinally-adjustable fingers arranged to enter the barrel and impinge against the edges of a nail-plate as the 7o latter is fed through said barrel, substantially as set forth.

2. The feed-barrel of a nail-cutting machine having the nose thereof provided with an opening in each of its sides, in combination with springlfmgers secured to the sides of the nose and having thickened portions that enter said openings, substantially as set forth.

3. The feed-barrel of a nail-cutting machine having the nose thereof provided with an 8o opening in each of its sides, in combination with slotted spring-fingers having their for. ward ends arranged to enter the openings in the barrel-nose, and set-screws that enga-ge the slots in the fingers and sides of said nose, substantially as set forth.

In testimony that Iclaim theforegoing Ihave hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence of two witnesses.

JONATHAN PILKINGTON.
